I have been thinking of adding an AK to my A4 but as far as I understand it, they really thus far cannot be fully “polychained”, am I correct on this? All you can do is sync them via midi is what I thought but am open to being corrected on this.

It would be nice if two A4’s or an A4 and AK could be chained so they fully then act as an 8 voice beasty.
